12102A102FAT2A

The 12102A102FAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components for industrial and commercial applications. This component belongs to the 1206 package family, a standard surface-mount form factor widely used in modern PCB designs where space efficiency and manufacturing automation are priorities. Multilayer ceramic capacitors like this part are fundamental building blocks in electronic circuits, serving critical functions including energy storage, AC coupling, decoupling, filtering, and noise suppression. The 1206 package size offers a practical balance between component footprint and handling ease in automated assembly processes, making it suitable for a broad range of industrial equipment, consumer electronics, telecommunications infrastructure, and power management systems. AVX's MLCC offerings are recognized for consistent quality and reliable performance across demanding industrial environments. The 1206 package format is one of the most commonly specified in modern electronics because it provides adequate capacitance density while remaining compatible with standard pick-and-place assembly equipment and solder reflow processes. This standardization also means engineers can source alternatives from multiple qualified manufacturers if supply chain flexibility is needed. Engineers typically specify components from AVX's capacitor portfolio when designing circuits that require stable performance under temperature fluctuations, high-frequency operation, or exposure to vibration and thermal cycling. The multilayer ceramic construction provides excellent frequency response characteristics and low equivalent series resistance (ESR), which are important in switching power supplies, RF circuits, and high-speed digital applications. When choosing a specific MLCC like the 12102A102FAT2A over alternatives, engineers consider several factors including the required capacitance value, voltage rating, temperature coefficient of capacitance, the dielectric material class, and frequency response characteristics. AVX's various MLCC series use different ceramic dielectric formulations—such as X7R, X5R, and Y5V—each offering different trade-offs between capacitance stability, temperature range, and maximum capacitance density. The 1206 case code also provides advantages in circuit board layout, as it's large enough to handle lead-free solder processes without excessive risk of tombstoning or other manufacturing defects, yet small enough to enable compact PCB designs. This makes it an economical choice for volume production runs where manufacturing reliability directly impacts cost of goods sold. For applications requiring high reliability in automotive, industrial control, medical devices, or telecommunications equipment, specifying established manufacturer components like those from AVX's catalog provides traceability, consistent quality documentation, and access to technical support resources that can be essential for mission-critical designs.
